Description

  The present invention relates to a control technology for video equipment and the like based on a vendor ID.

  In recent years, digital devices equipped with HDMI (High Definition Multimedia Interface) (registered trademark), such as TVs, DVD players, HD DVD players, HD DVD recorders, and AV amplifiers, have become widespread. HDMI can transfer video and audio without compression. In addition, the HDMI-CEC (Consumer Electronics Control) function allows each video device connected to the TV to be operated using a TV remote control.

  The HDMI-CEC function described above varies depending on the HDMI version, but currently includes the One touch play, System Standby, Remocon Path through function, and the like. The HDMI-CEC mandatory function works when devices that are considered HDMI CEC compliant are connected, but there are combinations of options and vendor-specific functions that work or do not work.

Various proposals have been made regarding such HDMI-equipped devices. On the display device side, the manufacturer code and the device code are read from all video devices connected to the display device to create a connected device list table, and when the user performs a remote control operation toward the display device, A receiving interface that receives a remote control code that is issued, searches the connected device list table for a match with the manufacturer code and device code included in the remote control code, and is connected to a video device that matches the manufacturer code and device code A technique has been proposed in which the selector is switched so as to connect the display device and the AV data transferred from the video equipment is displayed and reproduced on the display device (see Patent Document 1).

  According to the above technique, the display device holds the connected device information of a plurality of video devices connected to the display device. That is, the display device accepts a remote control operation, and controls playback of AV data from video equipment such as a recording / playback device connected to the display device. Accordingly, there is no initiative on the video equipment side, and video equipment that has been excluded on the display device side cannot be controlled by the display device. That is, if the display device is limited to control the video device when the display device and the video device of the same manufacturer are connected, the video device of the manufacturer different from the display device (that is, the vendor ID of the display device) When the vendor ID of the video equipment is different), the display device cannot receive control corresponding to the vendor code. That is, with regard to the vendor-specific function, there are combinations that operate and combinations that do not operate.

  An object of the present invention is to provide a technique that enables video equipment having a vendor ID different from that of a display device to be controlled by a vendor command corresponding to the vendor ID of the display device using the HDMI-CEC function.

  An information reproducing apparatus according to an embodiment of the present invention includes a vendor table including a vendor's official vendor ID and one or more registered vendor IDs, and a vendor command associated with each of the formal vendor ID and the registered vendor ID. Storage means for storing, connection means for connecting to a counterpart device for transmitting video, audio, and a vendor command, detection means for detecting a vendor ID of the counterpart device connected via the connection means, The formal vendor ID and the registered vendor ID included in the vendor table are compared with the vendor ID of the counterpart device, and the temporary vendor ID of the local device selected from the formal vendor ID of the local device and the registered vendor ID. Vendor ID control means for transmitting one of the above to the counterpart device, and the vendor table Irradiation and, based on the vendor ID of the partner device, and a motion control means for controlling the interpretation work vendor command from the partner device to be input through the connection means.

  An information reproduction method according to an embodiment of the present invention detects a vendor ID of the counterpart device connected via a connection unit connected to the counterpart device in order to transmit video, audio, and a vendor command. A formal vendor ID and one or more registered vendor IDs, and a formal vendor ID and the registered vendor ID of the device in a vendor table including a vendor command associated with each of the formal vendor ID and the registered vendor ID. Compares with the vendor ID of the counterpart device, and transmits either one of the vendor's formal vendor ID or the provisional vendor ID selected from the registered vendor ID to the counterpart device, and refers to the vendor table Based on the vendor ID of the counterpart device, the vendor from the counterpart device input through the connection unit To control the interpretation of the command works.

  ADVANTAGE OF THE INVENTION According to this invention, the technique which enables control of the video equipment of vendor ID different from a display apparatus by the vendor code corresponding to the vendor ID of the display apparatus by an HDMI-CEC function can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  When multiple HDMI devices are connected with HDMI cable and these HDMI devices have HDMI-CEC function, first, as a preparation, if you need to set the operation compatible with HDMI-CEC of each model, HDMI-CEC It is necessary to set the corresponding operation to valid.

The AV amplifier 2 is connected to the HDMI terminal 11 of the TV monitor 1, and the HD DVD player 3 is connected to the HDMI terminal 12 of the TV monitor 1. Further, the HD DVD recorder 4 is connected to the HDMI terminal 21 of the AV amplifier 2.

  FIG. 2 is a diagram illustrating an example of an information reproducing apparatus such as the HD DVD player 3 or 4. As shown in FIG. 2, the information reproducing apparatus includes a user operation input unit 31, a CPU unit 32, a storage unit 33, a disk drive unit 34, a signal processing unit 35, an HDMI 36, and a network I / F 37.

  Further, the CPU unit 32 includes a vendor ID reception unit 321, a vendor ID detection unit 322, a vendor ID determination unit 323, a local vendor ID switching unit 324, a vendor ID transmission unit 325, and a vendor ID registration unit 326.

  The user operation input unit 31 inputs a user operation to the CPU unit 32. For example, information necessary for registration of a vendor ID, which will be described later, is input to the CPU unit 32. The storage unit 33 functions as a storage unit that stores the official vendor ID and registered vendor ID (vendor ID table) of the device itself. The HDMI 36 functions as a connection unit that connects to a counterpart device in order to transmit video, audio, and a vendor command. The CPU unit 32 detects the vendor ID of the partner device connected via the HDMI 36, and based on the registered vendor ID registered and the detected vendor ID of the partner device, the registered original vendor ID and registration of the own device It functions as a vendor ID control means for transmitting any one of its own provisional vendor IDs selected from the vendor IDs to the counterpart device. Details of the vendor ID control by the information reproducing apparatus will be described in detail later. The disk drive unit 34 reads information from a disk such as a DVD or records information on a disk such as a DVD. The signal processing unit 35 decodes information read by the disk drive unit 34 and transfers it to the HDMI 36, or encodes information input via the HDMI 36 and transfers it to the disk drive unit 34.

  FIG. 3 is a diagram illustrating an example of a vendor table stored in the storage unit 33. As shown in FIG. 3, the vendor table includes its own vendor ID, a plurality of registered vendor ID_A, registered vendor ID_B, and registered vendor ID_C. Further, vendor commands (play, FF, REW, REC, ↑, →, ←, ↓,...) Associated with these formal vendor ID, registered vendor ID_A, registered vendor ID_B, and registered vendor ID_C are stored. .

  FIG. 4 is a diagram illustrating an operation at the time of HDMI connection.

  (1) Check that the logical address “(TV)” has not been acquired by <Polling Message> at the following timing.

(1-1) Power OFF (power is not supplied) → Standby (sub-microcomputer energization) timing (1-2) Standby → Power ON (main microcomputer energization) timing (1-3) + 5V Power energization detection timing ( (Assuming that it is connected to an amplifier with two HDMI outputs later)
(2) When the logical address 0 (TV) is in use, the logical address (Free Use) is acquired. If the logical address (Free Use) cannot be acquired, the logical address (Unregistered) is operated.

  (3) When a logical address can be acquired (other than logical address (Unregistered)), <Report Physical Address> and <Device Vendor ID> are broadcasted to notify the physical address, device type, and vendor ID.

  (4) A CEC device is searched when the set is activated, and device identification is performed for each discovered device.

  FIG. 5 is a flowchart showing an example of operations from obtaining a vendor ID to replying by the information reproducing apparatus shown in FIG.

  As shown in FIG. 5, the vendor ID is sent from the TV monitor 1 side at the time of standby, when the power is turned on, or at other necessary timing. The vendor ID receiving unit 321 of the information reproducing apparatus receives the vendor ID (the vendor ID of the partner device) sent from the TV monitor 1 side (ST1). The vendor ID detection unit 322 of the information reproduction device compares the registered vendor ID stored in the storage unit 33 with the vendor ID of the counterpart device, and the vendor ID determination unit 323 of the information reproduction device determines which vendor ID of the TV monitor 1. Is connected. After that, the vendor ID transmission unit 325 transmits to the TV monitor 1 either one of the original vendor ID stored in the storage unit 33 and the provisional vendor ID of the own device selected from the registered vendor ID. The details are as follows.

  When the original vendor ID stored in the storage unit 33 and the vendor ID of the counterpart device are the same (ST2, YES), the vendor ID transmission unit 325 responds to the device authentication command from the TV monitor 1, The official vendor ID of the own device is transmitted (ST3).

  When the formal vendor ID of the own device stored in the storage unit 33 is different from the vendor ID of the counterpart device (ST2, NO), and the vendor ID of the counterpart device matches the registered vendor ID stored in the storage unit 33 ( (ST4, YES), the vendor ID switching unit 324 switches the vendor ID of its own device from the official vendor ID to the matching vendor ID (that is, the same vendor ID as the partner device vendor ID). In response to the device authentication command from the TV monitor 1, the vendor ID transmission unit 325 transmits the matched vendor ID (that is, the same vendor ID as that of the partner device) as the temporary vendor ID of the own device (ST5). . The TV monitor 1 receives the transmitted temporary vendor ID as an official vendor ID. On the TV monitor 1 side, the formal vendor ID and the temporary vendor ID cannot be distinguished.

  When the formal vendor ID of the own device stored in the storage unit 33 is different from the vendor ID of the counterpart device (ST2, NO), and the vendor ID of the counterpart device does not match the registered vendor ID stored in the storage unit 33 ( (ST4, NO), the vendor ID transmission unit 325 transmits its official vendor ID in response to the device authentication command from the TV monitor 1 (ST6).

  That is, the information reproducing apparatus returns the same vendor ID as the vendor ID of the TV monitor 1 to the TV monitor 1 having the same vendor ID as the vendor ID stored in the storage unit 33. In other words, the information playback device is a product of the same vendor as the TV monitor 1. In other words, the TV monitor 1 recognizes the information reproducing apparatus as a product of the same vendor. Therefore, the information reproducing apparatus can be operated by a vendor command sent from the remote controller on the TV monitor 1 side.

  For example, if the vendor ID transmitted from the TV monitor 1 matches the registered vendor ID_B (see FIG. 3), the information playback device matches the registered vendor ID_B (that is, the vendor ID of the partner device). The same vendor ID) is transmitted as the temporary vendor ID of the own device. Further, the CPU 32 of the information reproducing apparatus refers to the vendor table (a vendor command associated with the registered vendor ID_B) and, based on the vendor ID (= registered vendor ID_B) of the counterpart device, the TV via the HDMI 36. Interprets vendor commands sent from the monitor 1 side and controls operations (play, FF, REW, REC, ↑, →, ←, ↓,...).

  Next, registration of a vendor ID will be described. The vendor ID registration unit 326 registers the vendor ID, and the storage unit 33 stores the vendor ID registered by the vendor ID registration unit 326.

  For example, at the time of initial setting, the vendor ID registration unit 326 of the information reproduction apparatus displays a vendor ID registration screen (for example, an OSD (On Screen Display) screen) on the TV monitor 1. The vendor ID registration unit 326 of the information reproducing apparatus registers the vendor ID of the connection target TV monitor 1 input from the vendor ID registration screen via the user operation input unit 31. After registration, as described above, the information reproducing apparatus can return the registered vendor ID to the TV monitor 1 of the connection partner as if it were the vendor ID of its own device.

  Alternatively, the vendor ID registration unit 326 of the information reproducing apparatus can register the vendor ID and the vendor command corresponding to the vendor ID transmitted from the TV monitor 1 of the connection partner via HDMI-CEC. In this case, the vendor ID registration unit 326 of the information reproducing apparatus displays the vendor ID registration screen on the TV monitor 1 and determines whether the vendor ID transmitted from the connected TV monitor 1 and the vendor command corresponding to the vendor ID can be registered. After confirming with the user, the vendor ID and the vendor command corresponding to the vendor ID are registered. After registration, as described above, the information reproducing apparatus can return the registered vendor ID to the TV monitor 1 of the connection partner as if it were the vendor ID of its own device.

  Further, when an information reproducing apparatus having a different vendor ID and the TV monitor 1 are connected, when the information reproducing apparatus receives a vendor command from the TV monitor 1, the "TV monitor 1's" If the vendor ID of TV monitor 1 is a registered vendor ID in response to the confirmation of “Do you support vendor commands?”, Reply “Supported” to TV monitor 1, then TV monitor 1 1 may correspond to a vendor command transmitted from 1.

  In the above description, the present embodiment has been described by taking the HDMI-CEC function as an example, but the path for sending the vendor command may be via LAN, via Bluetooth (registered trademark), or via USB connection.

  In the above description, the case where the information reproducing apparatus returns the same registered vendor ID as the vendor ID of the TV monitor 1 according to the vendor ID of the TV monitor 1 has been described. That is, the case where the information reproducing apparatus is a product of the same vendor as the TV monitor 1 has been described, but the present embodiment is not limited to this. For example, in response to the question “Does it correspond to the vendor ID?” From the TV monitor 1, the information reproducing apparatus simply returns “corresponding”, and the vendor ID of the information reproducing apparatus and the TV are actually set. Even if the vendor ID of the monitor 1 is different, the TV monitor 1 may transmit a vendor command to the information reproducing apparatus.

  Further, the network I / F 37 of the information reproducing apparatus may acquire a vendor ID and a vendor command corresponding to the vendor ID and register them in the storage unit 33. That is, the network I / F 37 may connect to the network server of the partner device vendor and acquire the vendor ID of the partner device and the vendor command corresponding to the vendor ID from the network server. This eliminates the need for the information reproducing apparatus to always store many vendor IDs and vendor commands. In some cases, the information reproducing apparatus may store only the vendor ID and vendor command of the counterpart device, and delete the stored vendor ID and vendor command of the counterpart device if the connection is canceled. As a result, the storage resources of the information reproducing apparatus can be effectively used, and the compatibility with new equipment is excellent.

  Conventionally, when the information reproducing apparatus connected to the TV has a vendor ID different from the TV vendor ID, the information reproducing apparatus connected to the TV is controlled by a vendor command associated with the TV vendor ID. I could not. In addition, the operation of the information reproducing apparatus may be restricted on the condition that the connected TV and the vendor ID of the information reproducing apparatus are different.

  According to this embodiment, even if the information reproducing apparatus connected to the TV returns a vendor ID that is the same as the TV vendor ID even if the vendor ID is different from the TV vendor ID, the same information as the TV vendor ID is returned. As with a device having a vendor ID, an information reproducing apparatus connected to a TV can be operated only by a TV remote control. That is, the information reproducing apparatus can interpret and operate a vendor command corresponding to the TV vendor ID.

  Further, the information reproducing apparatus can cope with a connected device other than the previously registered vendor ID by learning the vendor ID of the connection partner.

  The HDMI-CEC part is described in the version of the HDMI standard. However, the vendor command corresponding to the vendor ID is left to the specifications of each company. Conventionally, when a player or recorder from a manufacturer different from the manufacturer of the TV monitor or projector is connected, there has been inconvenience that HDMI-CEC vendor commands cannot be handled. According to the present embodiment, this inconvenience is eliminated, and even if a monitor and a player of different vendors are connected, it is possible to operate according to the vendor command by HDMI-CEC.

  In addition, this invention is not limited to the said embodiment, In the implementation stage, it can change variously in the range which does not deviate from the summary. In addition, the embodiments may be appropriately combined as much as possible, and in that case, the combined effect is obtained. Further, the above embodiments include inventions at various stages, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent elements. For example, even if some constituent requirements are deleted from all the constituent requirements shown in the embodiment, the problem described in the column of the problem to be solved by the invention can be solved, and the effect described in the column of the effect of the invention Can be obtained as an invention.
